The freqs array in freq_info struct has RTE_MAX_LCORE_FREQS elements,
yet the code can attemtp to look at the index at POWER_MANAGER_MAX_CPUS,
which may be greater than RTE_MAX_LCORE_FREQS. Fix to limit index to
RTE_MAX_LCORE_FREQS.

It seems to have been fixed in another patch, isn't it?
It was not fixed in another patch, although I can see the confusion.
A previous patch made the #defines more consistent, and
POWER_MGR_MAX_CPUS was changed to RTE_MAX_LCORE on the affected line.
However, this was later revealed as a coverity issue, and was fixed in
this patch to be RTE_LCORE_MAX_FREQS, which is the size of the array
it's trying to index into.
So looking at RC2, this patch is still needed.
Rgds,
Dave.
